In catalyzing apparatus, the combina- 10o tion with a plurality of catalyzing chambers, of a jacket surrounding the same, a'reservoir connected to the jacket, means for heating the reservoir, a casing surrounding the jacket, fins on the exterior of the jacket, means for admitting aheat modifying agent to the casing, means for permitting the outflow of such agent from the casing, and means controlled by the temperature in the casing for governing the flow of; such 'medium through the casing.

3. In catalyzing apparatus, the combination with a catalyzing chamber, of a casing enclosing the same, a jacket in the casing en closing the catalyzing chamber, a reservoir outside the casing having communication with the jacket, a heater for the reservoir, a casing enclosing the reservoir, and means for varying the temperature within the latter.

4. In catalyzing apparatus, the combination with a plurality of catalyzing chambers, of a jacket surrounding the same, a reservoir connected to the jacket, means for heating the reservoir, a casing surrounding the jacket, fins on the exteriorof the jacket, means for admitting a'heat-modifying agent to the casing, means for permitting the out flow of such a ent from the casing, means controlled by t e temperature in'the casing or governing the flow of such medium through the casing, a casing surrounding the reservoir, means for 'admltting a temperature modifying medium to the latter means and permitting its escape therefrom, and means for controlling the said medium.

5. In a catalyzing apparatus the combination which comprlsesa plurality of parallel catalytic chambers, means for retaining a continuous bath of liquid around said chamers, a reservoir external to said catalyzing chambers, means permitting the bath liquid surrounding the catalyst chambers to flow to and from said reservoir, a casing surrounding said reservoir, and means permiting a gaseous mediumto' pass between said casing and said reservoir.

6. In a catalyzing apparatus according to claim 5, means for applying heat to said reservoir.
